Ah, my apologies, ODF.  I didn't realize this was never intended to be a user/newbie-friendly figure, but a learning/teaching platform instead.  How I could have read all these pages and missed the point . . . . [sigh] well, it wasn't the first time that happened, and doubtless won't be the last.  [wry smile]  My misconceptions are my own, and not anyone else's fault.

Again, thanks for all of your work, as well as everyone else who contributed to Antonia!
